My invention relates to hot-watcr-circulatiug apparatus for heating railway-cars and other chambers, and has for its object the improvement ofthat class of heaters whereby explosion from confined steam is less liable to occur, the circulating medium is more quickly heated, the construction oftheparts simplified, and the cost oftheirprodnction made cheaper, and the general operation of the heating apparatus rendered more satisfactory; and it consists in the construction, as well as in a combination, of parts hereinafter particularly described,and then sought to bespecilically dedried by the claims.

In the accompanying drawings, the letter A.

elsewhere, as found most convenient or desie I able.

The stove comprises a body, E, and jacket its sides and top and the stove-body, is a boiler,

I, having a series oftubes, a, passing; vertically through it, and provided with an inlet-port, b, for the eutranceof water from the return-pipes C, and with an exit-port, c, for the passage of the heated water therefrom to the supply-pipe U, the inlet and exit ports being separated from each other bya partitioind, around which the water may circulate. The boiler is cut away or recessed, as shown, at the point in front of the stove-door, so as to permit the in troduction of fuel to the fire-pot. Thesupplly pipe extends from the boiler exit-port toares= ervoir J shown in 1-i".7 into which ito can so as to supply the reservoir with heated wa ter. The water passes from this reservoir through another section of the pipe U, as shown in Fig. 7, to the radiator B, and after passing through the radiator it passes by the return-pipe 0 back again to the boiler, where it is again heated to be circulated, as before. I prefer to use the reservoir 3. as it, stores a quantity of heated water to keep up the circn= lation; but .I may dispense with it, and connect the two sections of the supply-pipe by an elbow or T-conpling, K,.as shown in Fig. 1, which will permit a continuous circulation through the pipes, and at the same time ad mit of the application of my device for preventing dnnger of explosion while removing or replenishing the water in the supply-resew voir I). This reservoir is located on top of the car, and connects by means of a pipe, IM,

with thc distributiugreservoir, or elbow or T-conpliug, or'directly with the boiler. The pipe M is provided with a valve, N, near the reservoir or coupling, and may have an index, O, to indicate when the water in the supply-reservoir gets so low as to need replen- 2 erases I the gases or steam toescail: This is an portant feature.

The radiator B is comp'ois'fi f base divided into chambersf bjilh h h d transverse partitions. I; and i, cPhlmhmcatlhg with one another through a h tfa f i-{ tubes, Q, every two tubes of the SPIRES helhg connnccted together at the 1 hi 1 R, and placed so that one tub will p n 5 one chamber, and the other il h f l h chamber, whereby a free cnw tained through the chambelhahd tubes: the water entering the first end t thmhgh a port,j, from the supply-pit and Passing thence through the vertical i fi thmllgh the seriesot' chambers, and theil out through the port is into the return-pipe Q and hack the boiler. The upper'part ofthhl l shlelded by a hinged cover, S, and ea elhOw 1$l)F0- vided with a valve, 1, for the es of w from the tubes.

In order to ventilate the Gtiik I h P p T, from the outside of the teilh the Car it has an elbow, as shownltlO t0 the side of the heater, where it i caused to municate with the hot-air sij between h body of the stove and its jarli so that h troduced air will be heated a fl nted throughout the car by lll 0f fi l To prevent dust and cindel from helhg ried in to the space between ill? SYOYB hotly a jacket, I provide the ventilall l ll with a pocket, 111, preferably h m the llolhc of its entrance into the hut- 1 to f ceive the cindcrs carried doiil the l ll which may be removed through till l l g Close-d either by a cap, door, or cov't it To insure l passage of the cinders past th entrance to the bot-air space and into the ar s} l h fleeting-shield, a, over the i l t-i lh the jacket, so that the air and i- 'l" D first into thepoclret, where the Binders l posit, while the air will pass ill fi t0 and the hot-air space. This consif 0f lilting-tube may be employed other fOPlhS 0f stoves than hot-water radiate, h whilhel" the air introduced through t 1% f heating and ventilating or chi) Yehtlhltlhg purposes.

To prevent the cntire-revohl 0f the 100king-tongne to the door and ti hhow the door is locked, I cast with W: secure i suitable means to the inside! the a boss, T, formed with should d 101111 a lug, p, on the heel of the it 50 h glen the tongue is turned ti 'q a revolution in either direction the lug will strike against the shoulder andlprevent the tongue from being turned any farther in; that direction. When the lug strikes againstoneshonlder the door is locked,,and when against the other shoulder it is unlocked.

In willbe observed that the boss 1" is on a 1 log in the edge of the door, and thatthe tongue U tits into a recess formed in the body of the stove, so that when the tongue is turned upward it catches against the inside of the stovebody, justabove the recess or slot. 2

A catch or lug, q. is formed on the inside 0 the door, near one edge, so as to tit. into a recess or slot in the stove-body to aid in holding the door closed, and a second lug, q, is formed near the other edge, so as to bear against the edge of the'stove-body when the door is closed.

These two lugs, when the door is closed, bear against the edges of the stove body and strengthen the door, so as to brace it against lateral jars that mightotherwise throw itopen.

The outside flange, 1', of the jacket-door is recessed, so that when the door of thejacket and the door of the stove-bod y are both closed the-arm of the looking-tongue will fit in the recess of the jackebdoor.

The construction of the two doors and the application of the locking-tongue and its arm is such, as shown, that thejaclret-door cannot be closed and fastened unless the door to the stove-bod y is closed and locked. Consequently the outer door cannot be closed and the inner door by carelessness be left unlocked.

To further guard against the possibility of the outer door being closed without the inner door being locked by the outer door slipping past the thumb or finger piece of the arm of the tongue, I form a lug, s, on one side of the arm quite close to the thumb-piece, as shown, so that the flange of the jacket-door must strike the lag and hyit be prcven ted from closing unless the inner door is closed and locked.

In order that the fire-grate may be shaken without opening the doors, which would allow the ashes and dust to scatter,lpass arod, V, through both jackets and stove-body, and pivot a hook, t,to its inner end and engage the hook with the arm a of the grate, so that by pushing in and drawing out the rod the grate tion with the grate-arm, and the rod may be made removable from the jacket and stove by providing its outer end with a screw-cap or knob,

By setting the boiler on the tire-pot it can be readily removed when desirable for any purpose, and by leaving a space on all sides and top-and bottom of same, and passing tubes through it, the water is more quickly heated than under other constructions.

Instead of using the T-coupling or elbow, or even the reservoir J, the supply-reservoir may be connected directly with the boiler I, as shown in Fig. 2, and two deflecting-plates, instead of one, may be used at the air-opening into the stove above the pocket.

I reserve the right to make a separate application for the construction of radiator shown and described.

I reserve the right to make a separate application for the grate provided with a detachable shaking-rod, in combination with the pipes, and theradiator havingaseriesofchambers in its base communicating with one another by upright tubes connected together at the top, each set of tubes being provided with a valve in the connecting part for permitting the escape of air, substantially as set forth.

2. The stove provided with a door having a revolving locking-tongue, in combination with a jacket having a door provided with a recess adapted to receive the arm of the lockingtongue, substantially as and for the purpose set forth.

3. The stove provided with a door having a revolving locking-tongue, with a lug on its arm, in combination with a jacket having a door provided with arecess adapted to receive the arni of the locking-tongue, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
